A lovely twining climber up to a metre or more in the Pseudocodonopsis group with small (about the size of periwinkle, hence the name) deep violet blue saucer shaped flowers fading slightly towards the centre giving the impression of a faint ring. Although smaller than Cc forrestii and grey-wilsonii it is just as beautiful and, like its cousins, will perform well in a pot. The leaves are toothed and an early diagnostic is the non-clasping calyx lobes when in bud.
The seed is small and light brown.
